Kim Dotcom, the file-sharing kingpin indicted on criminal copyright infringement allegations in the United States, is suffering a setback in his purported quest to build a followup site to Megaupload, which U.S. authorities shuttered in January. We're skeptical that Dotcom would unveil a new file-sharing service as he awaits his potential extradition from New Zealand to the United States. But the domain for his alleged new site -- me.ga -- has been seized by the African nation of Gabon, where it was hosted. Dotcom unveiled the domain last week and said the new, encrypted site was to open soon for business.
